I already contacted customer service 2 days ago but have not yet received a response, so I thought I'd try here.
I'm on Android. I made a purchase for the Summoner package ($4.99, 10x heroic summons, some gems, gold, etc).
It was my first purchase ever. After confirmation, it just immediately crashed the game.
Now I crash on boot 100% and have not been able to play.
I didn't see if this was a known issue on the forums, so sorry if repost.
